I recently looked through the list of new DeveloperWorks articles and discovered an excellent article about how to use fragment-level statistics. Fragment-level statistics, which are a new IBM Informix version 11.70xC1 feature, affect the way UPDATE STATISTICS MEDIUM and HIGH operations gather data and generate column distributions on fragmented tables. For information on the circumstances under which you might want to use fragment-level statistics as well as details about setting up your system to use fragment-level statistics, see:

Incidentally, the DeveloperWorks article includes the following code example for forcing the use of fragment-level statistics. This example includes the new STATLEVEL property of a fragmented table. See the DeveloperWorks article and the Informix documentation for more details about the code:

You can use MQ messaging functions to enable Informix applications to exchange data directly between the application and IBM WebSphere MQ. Applications can send and receive messages from local or remote queue managers that reside anywhere in the network and participate in a transaction.
